1. BEFORE YOU BEGIN
When you received, the sensor and transmitter, both should be thoroughly inspected for any sign of
damage by rough handling during transit.
If you have something to inquire, contact the nearest OVAL sales/service office in your district.
1.1 Confirming the Tag Information
Product code and major ratings appear on the meter nameplate. Make sure that the product you
received complies with the specifications in your order.


1.2 Transportation Considerations
(1) The OVAL flowmeter can best be transported to the installation site in the shipping container used for
transit from the factory.
(2) Avoid impact shocks and exposure to rainwater or other moisture during transit.
1.3 Storage Considerations
If the meter upon receipt is to be stored for extended periods of time before installation, unexpected
problems could arise. If such is the case, the following considerations should be taken;
(1) The flowmeter can best be stored in the original package used for transit from the factory.
(2) The place of storage should meet the following requirements:
●Free from rain and water.
●Free from vibration and impact shocks.
●With least temperature and humidity variation (around 25 °C and 65% R. H.)
1.4 Operating Conditions
In order to maintain the design metering accuracy and long service life, it is essential that the ratings,
such as the flowrate, density, pressure, and temperature be held within the specified limits. These
operating conditions are stated on the tag, and in Sections 2.3 "General Specifications" and 2.4
"Product Code Explanation" in this manual. Do not fail to make sure of them before placing the meter in
service.
●If the process fluid is corrosive, the meter materials must be considered for
compatibility.
●If you want a change in operating conditions, consult the factory.
●Some solid-mixed flows or some gas-mixed flows that are not homegeneous are not
measurable. Consult the factory.
1.5 Precautions at Installation
CAUTION:
To ensure accurate and stable measurement, the Coriolis flowmeter should be installed
in a location where pipeline oscillation will not exceed 0.3G.

L-718-8-E

1.6 Returning Equipment
If the meter must be returned to OVAL for any reason, follow these steps to ensure the most efficient
processing.
(1) Clean the unit and flush out the tubes without fail and pack the sensor unit carefully. Fully document
the fluid. Inadequate information will delay handling of the meter. ( Fill in the forms prepared on
pages 64 and 65)
(2) Enclose complete information about the material being returned including model and serial number,
the reason for return, return address, and full documentation of the type of fluid.
(3) Pack the equipment carefully, using the original packing if possible.
(4) Return the complete flowmeter, including the remote electronics unit with all of the circuit boards and
associated parts.
Remove the conduit connections and all other parts not originally shipped with the meter.
IMPORTANT
Be sure to remove the accumulation of foreign matter on the inner walls of the sensor unit
completely. Because the sensor unit cannot be disassembled, OVAL will not be able to
handle residue inside the tubes and service your meter.
2. GENERAL
2.1 General
Our concentrated effort in developing true state-of-art measuring tools and specialized manufacturing
experience in Coriolis technology has resulted in this ULTRAmass MKII (ULTRAmass Mark II), a top-
performance, easy-to-use, general-purpose flowmeter.
It consists essentially of a high-performance sensor and a transmitter (CT9401).
The CT9401, a microprocessor-based transmitter for making process flow measurement, transforms the
signal from the sensor into an analog signal output (4 to 20mA) and a pulse output.
2.2 Features
(1) Outstanding accuracy (reading accurate to ±0.1% ± zero stability error with liquids) and high
sensitivity (measuring range 1:200).
(2) Broad flow range at low pressure loss.
(3) Accurately measures density and temperature besides mass flowrate.
(4) Constructed virtually free from any pocket to hold standing process fluid (installed in a vertical line)
for maximum ease of cleaning.
(5) Stainless steel or Hastelloy C sensor housing accepts a wide variety of process fluids.
(6) Lightweight and compact design with high mechanical rigidity offers ease of handling, reduces
space requirements, and contributes to increased safety of the process.
(7) Transmitter in either integrally mounted and separately mounted (locally separated) type to suit your
particular application.
(8) With a touch panel, selecting the transmitter display menu items, such as the flowrate, density, and
temperature, is simple.
(9) Explosionproof construction permits installation in hazardous locations.
(10) Models conforming to the high pressure gas safety laws also available.

Flowrate during the test (kg/min)
CAUTION: 1. For applications of volume flow measurement subject to taxation or transactions,
consult factory.
2. In gas measurement, the maximum permissible flow velocity varies with
the kind of gas and certain gases may be unacceptable for measurement.
In such a case, consult the factory.
2.3.4 Pressure Losses
◎How to determine pressure loss
(1) Find the pressure loss coefficient C from the flowrate (kg/min.) and viscosity of parameter (mPa・s).
Dividing this value C by specific gravity d (1 for water) gives the pressure loss, or
C
P ＝－－－ (MPa)
d
For liquids with viscosities below 1 mPa・s,usethecurveμ＝1.0 mPa・s.
(2) For high-viscosity liquids not shown in the graph, calculate the pressure loss by the following
equation:  μ21
P2＝C×－－－×－－
 μ1d
where P2: Pressure loss of high-viscosity liquid (MPa)
 μ2: Viscosity of high-viscosity liquid (mPa・s)
d: Specific gravity of high-viscosity liquid (1 for water)
 μ1: Maximum viscosity shown in the graph (mPa・s)
C: Pressure loss coefficient found from the maximum viscosity curve at a given
flowrate (kg/min.)
